Being trapped on Europa is a pretty serious problem

So now we know where Adrian Veidt has been. I thought he was on the moon after that clever scene change last episode that seemed to hint at it, but he's a lot more screwed than that. Seems like he was well aware of his location though. And he must've taken some readings from within his little bubble world to know how to time that little excursion for when the orbiting satellite would be passing directly overhead.

With all the materials he had at his disposal, why was it necessary to use frozen body parts to spell out his message? He could've fabricated nice bright letters or blocks to build them from and launched those onto the surface instead.

I'm still wondering who put him there. Was it Lady Trieu, or Dr. Manhattan? The Game Warden did refer to their god as "He" so I'm tending to think it's the latter. But who knows? If it is indeed Dr. Manhattan, escaping seems like an exercise in futility. If the blue guy cared enough to put him there in the first place he'd probably just scoop him up from Earth and send him back again.

I'm expecting him to get there though. At some point Veidt's storyline will obviously connect back to what's happening with the other characters.
